How do I set height of a camera/gameobject from another scene

Hey guys,

I want to give the player a choice to select the height of the VR camera game object from the menu scene based on the button they click

How do I pass/alter variables from one scene to another?

The camera game-object only exists in scene called Main but I want the player to be able to change the position based on what they choose in Main-Menu scene. Alternatively I could just do each button connecting to separate scenes with the heights I want but with a script that just changes the height of the game-object

On the menu I have this code attached to a button for an OnClickfunction

Code (CSharp):

1. public void Tall()
2.  
3. {
4.  
5. PlayerPrefs.SetFloat("HeightTall", 10.38f);
6.  
7. Debug.Log(PlayerPrefs.GetFloat("HeightTall").ToString());
8.  
9.  
10. //SceneManager.LoadScene("Main");
11.  
12. }

Once it goes into the next scene I have this line of code attached to the maincamera

Code (CSharp):

1. public GameObject MyVrCam;
2.  
3. public void Start()
4.  
5. {
6.  
7. PlayerPrefs.GetFloat("HeightTall");
8.  
9. MyVrCam.transform.position = new Vector3(0.0f, HeightTall, 0.0f);
10.  
11. }
12.  
13. }

I basically want the 'HeightTall' to be the new y position declared in the menu scene but that is being underlined as an error.
